Neural network applications in microwave engineering have been reported since the 1990s. Description of artificial neural
networks and their key issues, namely architectures, paradigms, training methods, data sets formation, learning and
generalization errors, learning speed, etc., in the context of…

It has been suggested there is a knowledge base that surrounds the use of 3D modeling within the engineering design process and correspondingly within engineering design graphics education. While solid modeling receives a great deal of attention and discussion relative…

Las realidades que marcan el recién iniciado milenio establecen inéditas señales paradigmáticas, las cuales acompañan el
devenir de la sociedad de la información y el conocimiento, aupando la aparición de originales nociones espaciales y temporales, conformantes de novedosos procesos…

Recently, many individuals have been faced with a transfer of learning issue, surrounding the move from one 3-D CAD system to another.  The purpose of this research was to test the hypothesis that, with minimal instruction, users can transfer their…

La recherche explore les dynamiques influençant la réussite scolaire des élèves montréalais originaires de l’Asie du Sud (Inde, Pakistan, Sri Lanka et Bangladesh) à l’école secondaire publique de langue française. En effet, au Québec, à cet ordre d’enseignement, parmi tous…

Engineering and technical graphics professionals have seen major changes in the content and the way we teach our students (Clark & Scales, 2000).  Today, professionals going into fields related to engineering/technical graphics require a broader knowledge of differing forms of…

ROI (Region of Interest) in an image or video signal contains important information and may be used for access control at various qualities using multiresolution analysis (MRA). This paper proposes quality access control method of compressed color image by modulating…

Spatial ability research has been approached from several psychological vantages since its beginnings in the late 1800s. This contribution attempts a summation of spatial ability research, beginning with a historical vignette and a major section on each psychological approach including…

La mayor producción e industrialización de alimentos exportables y destinados para el mercado interno argentino se localiza en la
región pampeana, donde también se concentra el grueso de la población y el mayor porcentaje de hogares con necesidades básicas
insatisfechas.…

Constraint-based modeling tools, as well as computer graphics tools in general, offer the user many choices in commands and techniques for creating graphics, which forces the user to have a strategy or plan as they proceed. The formulation of this…
